Results of the precision testing based on intraobserver variability (repeatability) and interobserver variability (reproducibility) in a clinical setting in canine patients.

Intra- and interobserver agreement of CT-based tibial angular measurements in a clinical setting in 34 dogs with a clinical diagnosis of patellar luxation that underwent preoperative CT examinations of both hind limbs for routine preoperative assessment and planning of surgical correction
	Intraobserver Agreement			Interobserver Agreement
Angle	Coefficient of variation for repeated measurements (%)	Overall mean	95% Confidence interval	Coefficient of variation for repeated measurements (%)	Overall mean	95% Confidence interval
Tibial torsion angle (TTA)	2.35	179.88	0.81 to 3.23	0.60	181.08	0.46 to 0.72
Tibial varus angle (TVA)	2.70	188.57	0.00 to 4.64	0.97	189.18	0.63 to 1.21
